To all whom t may concern.' V

' Be it known that we, ADELBERT R. GIB- SON and GEORGE H. FERGUSON, citizens of the UnitedStates, and residents of Los in the county of Los Angeles and State of California, nave invented certain new and useful Improvements in Vibratory Beds, of which the following is a specification.

Our invention pertains to vibrating and oscillating mechanism, and it has particular reference to means for imparting an undulatory, oscillating and reciprocating motion toa bed or a, mattress connected therewith, utilize such a structure 1n the process of treatment.

It is well known that in many diseasesor ailmentsmotion is a st1mulus, and if said character the eiect is a soothing one, and will tend to quiet the patient and divert his mind from his ailment. Of such nature are the vibratory treatments usually employed 85 but such processes are usually local, and are not, therefore, available for many cases. To this end, therefore, we have devised mechanism which is attached to andconstitutes part of the bed, which has a rhythmic movement laterally, and which has an oscillating and undulatory movement, so that the entire body is thus subjected to the motion, as now will be set forth in detail.

In the accompanying drawing Figure 1, is a top or plan view of a bed equipped with our improved vibratory means. Fig. 2, is a cross section of the mechanism showing the relative positions of the oscillating frame and links. Fig. 3, is a cross section of the mechanism showing position ofthe frame at one point in its movement, and'Fig. 4, is a top view of the head of the bedshowing the relative arrangement of the links and rockshaft for actuating the frame.

In constructing our invention it is to be understood that the mechanism is applicable to any bed-stead, but we prefer to have the bed-stead provided with strong horizontal side bars, 5, to carry the mechanism. The base of the mechanism comprises a pair of cross bars, 6, 6 at the head of the bed and asimilar pair of cross bars 7, 7 at the foot ofthe bed. Midway between the end of each of the bars 6, 7, is an upwardly-projecting bracket, 8, these brackets being designed to well defined and rhythmic receive La longitudinal rod 9, which serves as the plvoted bearing for the rocking frame. The rocklng frame comprises a cross bar 10, alongside the bracket 8, and a similar bar 11, alongside of the bracket on the cross bar 7,

The bars l0, 11, are preferablyof channel iron or L-bars, so as to form tracks or ways, on which are mounted wheels or castors 13, secured to the under side of a frame 14, this frame bein substantially the same size as the spring ed 15, lor the frame is of such size and character that the springs of a mattress may be secured and held thereby. It will be seen that th frame 14, is capable of moving laterally a limited distance on the channel bars 10, 11. In order to provide a means whereby the frame may thus be laterally moved We secure a bracket to one end of each of the cross bars 6, 7, so that it projects downwardly and these brackets carry a rock-shaft 16, parallel with the side bar 5, of the bed. At one end of the rock-shaft is a T-arm, one limb of which, as at 17, projects below the rock-shaft and the up er limb 18, thereof, projects above the shaflz). To the lower limb 1s hinged to one end of a connecting link 19,

the other end of the link connecting with a crank 20, of a motor 21. We prefer to use an electric motor for this purpose located beneath the bed, but this is optional as it may be operated by any well known means, or by a prime source of power entirely removed from the room, as for instance, by a flexible shaft. The upper limb 18, has a link 22, hinged thereto at one end and its e mattress-carrying other end is hinged to a" bracket 23, on the lower side of the cross bar 14,. The other end of the rock-shaft 16, has 'merely an upwardly-projecting arm similar to the link 18, and a link, similar to the link 22, is connected up with the other end of the mattress frame so both ends of the 'mattress frame will work in unity.. ment the mattressis moved laterally as 'the crank 2O turns, and with a view offimparting an undulatory motion to the mattress while it is this moving to and fro laterally, a pair of arms 24 project outv from the rockshaft 16 at right anglesto the 'T-arm 17, 18, and a pair of links 25, is hinged to the arms By this arrangeshould 24, and project upwardly and are pivotally att-ached to brackets 26 on the under sides of the cross-rocking-bars 10, 11.

From the aforegoing structure it will be seen that two distinct motions are directly imparted to the mattress supporting frame, one motion being a laterally reciprocating one through the action of the link 22, and the other a laterally rocking motion due to the pivotally hinged support on which the mattress frame rests, and these together produce a compound motion which resolves itself into an undulator or sinuous line, illustrated by the dotted lmes A, B, in Fig. 3.

In practice the motor is so geared to the mechanism that the motion is gentle and constant, and not nature and it is found that such a movement is more conducive to a restful effect in a patient than a sudden or pronounced motion, and it is important that the action be rhythmic in its character to produce the best results.

What we claim as new, is.

1. In an apparatus of the character described, a frame, a mattress thereon, and means on the frame for imparting an undulatory motion to the mattress.

2. In apparatus of the character described, a frame, a mattress thereon, and means on the frame for imparting a reciprocating and'rocking motion to the mattress. t

3. In apparatus of the character described, a frame, a mattress-thereon, and means on the frame for imparting a reciprocating and undulatory motion to the mattress.

4. In apparatus of the character described, a frame, a mattress thereon, means on the frame for laterally reciprocating and rocking the mattress and for producing a wave motion at its margins during the rocking and reciprocating movements.

5. In apparatus of the character described, a bed-stead, cross bars thereon, a longitudinally disposed pivotal shaft centrally along the cross bars, a rocking frame thereon, a

violent or abrupt in its' laterally movable mattress-supporting frame onsaid rocking frame, and means for imparting a reciprocating and rocking motion to said mattress-supporting frame.

scribed, the bed-stead, cross bars thereon, a longitudinal pivot shaft centrall through said bed-stead, a frame above sai bars pivotally secured to the pivot shaft, a mattress-supporting frame having castors which 6. In apparatus of the character deh permit the mattress-supporting frame to f a limited distance, a4 rockwith T-arms at one end, connected up with a motor and with the laterally-movable mattress frame, and means also connected with said rock-shaft imparting a rocking motion to said mattress-supporting frame. p

7. In apparatus of the character described, a bed-stead, cross bars secured thereto, a longitudinally disposed pivotf shaft centrallyalong the cross bars, a rocking frame above said bars pivotally joined to the pivot shaft, a mattress-carrying frame laterally movable on said rocking frame, a rock-shaft along one side of the bed-stead, having atone end, a crank arm connected up with the motor, and at eacn end a crank arm hinged to a link which connects with the laterally movable mattresscarrying frame, and an arm on the rockshaft at each end disposed at right angles to thevcrank arms which laterally reciprocates the mattress-frame, said arms having upwardly-projecting links which are hinged to the-mattress-frame to impart an undulatory and rocking motion while the frame oscillates to and fro.
